Hello,
Answer D
16x²y²-24xyz+9z² a perfect square trinomial
which
le square of the difference of 3z from 4xy.
Answer:
(8x − 2x ) + (−x − 2) = (5x − 3) − (4 −x ) a) Ecuación de Primer Grado. b)
Step-by-step explanation:
To find the x intercepts, we need to put the standard form equation into factored form.
Which two numbers multiply to -8 and add to -2?


So the factored form is

That means the x intercepts are at 
So now we have the x intercepts.
To find the vertex, we need to convert the standard form equation into vertex form.
The formula of vertex form is 
Since the a value in the standard form equation is 1, the a value in vertex form is also one.
The h value can be found using the formula 
Which comes out to
or 1.
To find the k value, we can just plug in what we got for h back into the equation.

So the vertex is
.
This also means the axis of symmetry is 
Finally, to find the y intercept, we plug in 0 for x and solve.

So the y intercept is
.
4 × ( x + 4 ) = 3 × ( 3 + 5 )
4 × ( x + 4 ) = 3 × 8
Divide both sides by 4
x + 4 = 3 × 2
x + 4 = 6
Subtract both sides 4
x = 2
